Map type: Pollution and Waste
This map shows the estimated annual freight railroad CO2 emissions for the year 2010 along the Mexico City to Montreal transportation corridor. Carbon dioxide emissions are measured as kilotonnes per kilometer. The transportation corridor is one of several that cross North America and the main freight railroads are based on the North American Environmental Atlas’ base layer. The railroads included are either rail links between major centers of population or major resource railways. Note there is no classification of rail lines.
The data were collected by the Texas Transportation Institute (TTI) from various sources as part of the Greening North American Transportation Corridors: Challenges and Opportunities paper published by the CEC (www.cec.org/freight). The major source for data on rail freight movement was the FHWA’s Freight Analysis Framework (FAF and FAF2). In Canada, the information included for the estimation came from the Canadian National Railway Company. In Mexico, the information that was used was from the Instituto Mexicano de Transporte (IMT). Other data sources encompass the Bureau of Transportation Statistics’ (BTS) National Transportation Atlas Database (NTAD) and North American Transborder Freight Data (NATFD), and other rail and freight databases.
